Well, that was the year they removed part of the crankcase drainage system, and in my opinion they didn’t run as well as previous years. But they ran better than later years when they managed to improve it so much they screwed it up good.
BTW, your motor is supposed to have a drain hose leading from the intake manifold to the lower, front bolt/nipple on the lower bypass cover.
